1 Summary
2 =======
3 
4 This README is about U-Boot support for Renesas's ARM Cortex-A9 based RMOBILE[1]
5 and Cortex-A9/A53/A57 based R-Car[2] family of SoCs. Renesas's RMOBILE/R-Car SoC
6 family contains an ARM Cortex-A9/A53/A57.
7 
8 Currently the following boards are supported:
9 
10 * KMC KZM-A9-GT [3]
11 * Atmark-Techno Armadillo-800-EVA [4]
12 * Renesas Electronics Lager
13 * Renesas Electronics Koelsch
14 * Renesas Electronics Salvator-X  M3
15 * Renesas Electronics Salvator-XS H3 ES2.0+
16 * Renesas Electronics ULCB M3 / H3 ES2.0+
17 
18 Toolchain
19 =========
20 
21 Either ARMv7 toolchain for 32bit Cortex-A9 systems or ARMv8 (aarch64)
22 toolchain for 64bit Cortex-A53/A57 systems. Currently we compile the
23 32bit systems with -march=armv5 to allow more compilers to work. (For
24 U-Boot code this has no performance impact.)
25 
26 Currently, ELDK[5], Linaro[6], CodeSourcery[7] and Emdebian[8] supports
27 ARMv7. Modern distributions also contain ARMv7 and ARMv8 crosstoolchains
28 in their package feeds.
